Ammonia test :
blood is put into a heparinized tube and packed in ice for transport to the laboratory. The specimen is stable only for about 20 minutes.
In mild liver disease, PT and aPTT
PT is prolonged but the aPTT is normal
Macroamylasemia – in vivo artifact
1% of randomly selected patients with no specific symptoms or disease states may have elevated amylase results

lipase ≥5× upper reference limit
Pancreatitis highly likely
Lipase : amylase ratio >3 (especially >5)
Alcoholic rather than non alcoholic pancreatitis
Macroamylase
Complex of amylase (usually S-AMY) with IgA, IgG, or other high molecular weight plasma proteins that cannot be filtered through the glomerulus due to its large size and is thus retained in plasma
